The Obamas reported paying $453,770 in federal taxes. They donated $245,075, or 14% of their income, to 36 different charities. Fisher House Foundation, a charity that works with veterans, took home the biggest single donation.

The president earns a salary of $400,000 for his day job. His paycheck was much higher because his books -- "Dreams From My Father," "The Audacity of Hope" and "Of Thee I Sing: A Letter to My Daughters" -- continued to register strong sales. But those sales were not nearly as strong as they were the year before.

Obama is donating the proceeds from the latest book, "Of Thee I Sing," to a Fisher House scholarship fund for children of fallen and disabled soldiers. This year, the contribution was $131,075.

The Obamas donated $15,000 to the Clinton Bush Haiti Fund, and $10,000 to the Boys & Girls Club of America.

The Bidens donated $5,350 to charity, in both monetary and in-kind donations, an amount equaling 1.4% of their adjusted income. The biggest donation listed on the tax return is a $1,400 donation to the Northern Virginia Community College Alumni Scholarship Fund.

Elizabeth Alexander, Vice President Biden's press secretary, issued a statement to CNN that emphasized that the Bidens also donate their time to charitable causes.

"The charitable donations claimed by the Bidens on their tax returns are not the sum of their annual contributions to charity. They contribute to many causes with their time, as well as their checkbooks," she said.
